Example of a graph of engine oil pressure (Y) Pressure in kPa (X) Calendar days (1) Baseline (2) Operating pressure (3) Setpoint (alarm)
Average the data for each day. Use a computer or graph paper in order to produce a graph of the data. Compare the new data to the baseline. This will help to reveal the trends of the engine performance.Illustration 1 shows that the engine oil pressure was near baseline (1). Later, the operating pressure was approaching setpoint (3). The trend of operating pressure (2) indicated that the condition required investigation before activation of the alarm.
Compare the new data to the data from previous months. This comparison will be useful for scheduling reconditioning for the engine.Monitoring the Trends of Oil Consumption
The consumption of lube oil depends on the following factors:
Engine load
Hours of operation
Type of oilMonitor the engine's oil consumption by calculating the Specific Oil Consumption on a daily basis. Be aware that the following conditions can produce misleading data on oil consumption:
Improper operation of the lube oil centrifuge
Inaccurate measurement of additions of oil
Leaking of lube oil
Overfilling of the oil sumpTo measure additions of oil accurately, use a meter to monitor additions of oil at the engine. Also, check the total oil consumption against the delivery of oil.Calculating Specific Oil Consumption
Use the equation that is in Table 2 in order to calculate the Specific Oil Consumption.
Table 2
Equation For Calculating the Specific Oil Consumption    
    O ? D     = BSOC    
    bkW-hr    
O is the liters of oil that have been consumed.    
D is the density of the oil. The density is expressed in grams per liter.    
bkW-hr is the kilowatt hours that have been produced during consumption of the oil.    
BSOC is the brake specific oil consumption. This is expressed in grams per kilowatt hour.    To calculate the BSOC, the bkW-hr must be known. Table 3 is an example for calculating the bkW-hr. The data in the example assumes the following conditions:
A meter was used to measure the fuel consumption of 1000
